Does a new column in a Common Data Model (CDM ) folder reflect automatically in a Power BI dataflow?
Hi Anonymous ,
When you add a new column to an existing table in the CMD folder, it is not automatically reflected in the Power BI data flow. You need to take additional steps to update the data flow to include the new column.
From my understanding, when new columns are added to a data source, they are not automatically updated to the Power BI data flow even after a successful refresh. To include the new columns, you may need to delete the existing table and rejoin it in the Power Query editor.

Hello, and thank you for your comment!
Actually, that’s an important point: dataflows created from CDM cannot be edited directly in the Power BI service. While you can consume them, editing their structure isn't supported.
Given this limitation, do you think I’ll need to drop the existing dataflow and recreate it for the new column to be reflected? We haven’t added the column yet, but I’m trying to anticipate or estimate the impact. Since we have several semantic models connected to this dataflow, dropping and recreating it would mean updating the dataflow ID in all of them, which could become a significant task.
Looking forward to hearing your thoughts!
